摘要： A power monitoring system uses a low loss reflective element to partially split the output laser beams from an array of laser sources, in a parallel configuration, to produce a monitor beams for each laser source. Each of these monitor beams may propagate within the reflective element in a lossless manner under total internal reflection and into one of a plurality of photodiodes that sense an optical characteristic such as output beam intensity, where this sensed signal is then used as part of a feedback control to control operation of the laser sources in the array.

摘要： A photodiode array includes a plurality of monitoring photodiodes capable operating in a voltage mode configuration each able to provide a voltage indicating an intensity of an incident light. Integrated with the monitoring photodiodes is a reference diode configured to produce reference voltages in response to reference currents supplied to that diode. The monitoring photodiodes and the reference diode may be integrated and have the same current-voltage characteristics and the same temperature, for example by fabricating them on the same substrate. The reference diode is supplied with the reference currents in dark manner, meaning without incident light impinging on the reference diode. The resulting reference voltages, the reference source currents, and the measured photo-voltage from the monitoring photodiodes are than used to determine an optical power value at any temperature within the operation temperature range.

摘要： To a laser that has no tracking error a desired laser modulation current to maintain constant Optical Modulation Amplitude (OMA) is closely proportional to the laser bias current, lb, at any temperature when the laser is under constant power according to embodiments. To a laser that has tracking error a desired laser modulation current to maintain constant Optical Extension Ratio (ER) is closely proportional to the laser bias current, lb, at any temperature when the laser is under constant power according to embodiments. This phenomenon is appears apply to many if not all types of lasers. A laser modulation control is provided that determines a modulation current based on the laser bias current. Thus, embodiments may maintain performance and compensate for temperature changes without the need to actually measure temperature thereby eliminating the need for temperature sensors and their associated parameter vs. temperature look-up tables or dithering techniques used in the past.

摘要： According to embodiments of the present invention, an optical transponder includes a transmitter optical subassembly (TOSA). In one embodiment, the electrical ground of the TOSA may be DC-isolated from chassis ground of the transponder using a blocking capacitor that couples the AC signal path to VDD and that allows the case of the TOSA to float. In an alternative embodiment, the electrical ground of the TOSA may be DC-isolated from chassis ground of the transponder using a blocking capacitor that couples the AC signal path to VDD and a resistor that couples the DC bias level path to internal electrical ground or transponder case ground.
